This is a much better api than using tevent_schedule_immediate() with a NULL handler, while the tevent_context is still required as argument.

2023-10-13tevent: add support for TEVENT_FD_ERRORStefan Metzmacher6-80/+167
After 12 years we finally got TEVENT_FD_ERROR support :-) TEVENT_FD_WRITE event handlers never get errors reported instead the event handler is silently disabled. There are likely callers relying on that behavior, so we are not able to chance it. Now TEVENT_FD_WRITE can be used together with TEVENT_FD_ERROR in order to get errors reported without waiting for TEVENT_FD_READ. TEVENT_FD_ERROR can also be used alone in order to detect errors on sockets in order to cleanup resources.

2023-10-13tevent: let tevent_epoll.c use new generic mpx infrastructureStefan Metzmacher1-294/+263
This allows any number of event handlers per low level fd. It means the epoll backend behaves like the poll backend now. Signed-off-by: Stefan Metzmacher <metze@samba.org> Reviewed-by: Ralph Boehme <slow@samba.org>
2023-10-13tevent: add tevent_common_fd_mpx infrastructureStefan Metzmacher4-0/+390
Backends may require to map individual tevent_fd instances to a single low level kernel state (e.g. for epoll). This generic infrastructure adds helper functions using a generic (sub)part of struct tevent_fd. The new code will allow us to support more than 2 tevent_fd instances per fd, which makes sure all backends can provide a similar behavior. This will be important when we add TEVENT_FD_ERROR as a 3rd kind of fd event. The aim is to use this in order to replace the limited implementation we already have in tevent_epoll.c. As these helpers are typically called from within 'void tevent_fd_set_flags(struct tevent_fd *fde, uint16_t flags)' there's no way to report errors. So in order avoid additional error handling complexity the helpers try to avoid any allocations which may fail. It also means the logic in tevent_epoll.c doesn't have to change much. These are implemented as static line functions in order to avoid the function call overhead, which showed up in profiles of the early implementation.

2023-10-13tevent: introduce DLIST_DEMOTE_SHORT()Stefan Metzmacher1-0/+21
It turns out that the overhead of DLIST_DEMOTE() implemented as DLIST_REMOVE();DLIST_ADD_END(), is very high if the list contains only 1 or 2 elements. The next commits will make use of DLIST_DEMOTE_SHORT() for multiplexing multiple tevent_fd structures for a single fd and the most important and common case is a list with just one element.

2023-07-19tevent: introduce tevent_set_max_debug_level() (default TEVENT_DEBUG_WARNING)Stefan Metzmacher4-1/+55
Allow an application to decide which log levels it wants to get in the callback function passed to tevent_set_debug(). By default TEVENT_DEBUG_WARNING is the maximal reported level and TEVENT_DEBUG_TRACE message no longer reach the callback function by default. It seems Samba is the only consumer of tevent_set_debug(), so it should not be a huge problem, as Samba only reports TEVENT_DEBUG_TRACE message with log level 50 anyway. And future Samba versions will call tevent_set_max_debug_level() if needed. Note the change to tevent-0.14.1.sigs will be reverted with the release of tevent 0.15.0.
